Majid Ahmed won the place after turning his life around and achieving straight A grades at A level. The conviction was spent but he had to disclose it for a criminal records check for Imperial.
The decision, which comes as the government is considering a new strategy to encourage elite universities to take more students from less wealthy backgrounds, has been widely criticised. Ahmed should not have to bear the consequences of a youthful indiscretion for life and should have been given the chance to fulfil his ambition to become a doctor, critics say.
Imperial College says it was right to bar him and that decision had been made to uphold trust in the medical profession.
What is your opinion? Is Imperial being too harsh?
